To see if psychiatrists could can tell the difference between those who are sane and insane.
He claimed the IV was the words that the pseudo patients could hear.
Rosenhan and his confederates were pretending to be insane to gain admittance to hospitals.
Then they observed the behaviour of staff and participants without them knowing.
Public and private hospitals
8 fake patients- Rosenhan and his confederates
No history of mental illness
5 males, 3 females
All used a fake name
11 diagnosed with schizophrenia and 1 with manic depressive psychosis (bi-polar depression)
12 HOSPITALS WERE USED WITH 8 PSEUDO-PATIENTS AS SOME WENT TO MORE THAN ONE HOSPITAL
Once admitted they stopped showing signs of abnormality and started behaving ad they normally would.
They were told to convince staff that they were better and could be released.
They made notes of everything and began taking them in public places as ‘no-one seemed to care’.
They obeyed all instructions but did not take the medication (hiding it) but staff believed they were.
None of the patients were detected as fake- failure in diagnostic system.
Some actual patients were suspicious- 35 out of 118 patients voiced suspicions ‘you’re not crazy, you’re a journalist’
They were all eventually discharged with ‘schizophrenia in remission’
Minutes staff spent with patients
Number of times staff left the ‘cage’ (office)
Amount of eye contact from psychiatrists
How patients were treated- diaries
Felt a sense of powerlessness and depersonalistaion
e.g. hygiene and waste evacuation monitored and toilets had no doors
Verbal and psychical abuse to patients
e.g. ‘come on you mother****ers, out of bed’
Queueing for lunch- oral acquisitive behaviour (eager)
More likely to diagnose a healthy person as sick or a sick person as healthy- TYPE ONE ERROR
Better and safer to do this and misdiagnose rather than do nothing?
